As a rhetorical discourse in dialectic awareness, such is to be for of consisting categorical propositions, which can be represented as or, decomposed into a sequence of categorical syllogisms such that the conclusion of each syllogism except the last one in the sequence as a premise of the next syllogism in the sequence. An example is, All cats are felines, and, all felines are mammals, as all mammals are warm-blooded animals, therefore, all cats are warm-blooded animals. This Sorites may be viewed as composed of the two syllogisms. All casts are felines: All felines are mammals, therefore, all cats are mammals, and, all cats are mammals, and, all mammals are arm-blooded animals. A Sorites is valid if and only if each categorical syllogism into which it decomposes is valid. In the example, the Sorites decompose is valid. Again, the Sorites decomposition into two syllogisms in the mood, as Barbara, since any syllogism in Barbara is valid, the Sorites is valid.
It is, however, to what extent can analysis be informative? This is the question that gives a riser to what philosophers has traditionally called the paradox of analysis. Thus, consider the following proposition:
(1) To be an instance of knowledge is to be an instance of justified true belief not essentially grounded in any falsehood. (1) If true, illustrates an important type of philosophical analysis. For convenience of exposition, I will bear as the viewer to (1) is a correct analysis. The paradox arises from the fact that if the concept of justified true belief not been essentially grounded in any falsification is the analysand of the concept of knowledge, it would seem that they are the same concept and hence that: (2) To be an instance of knowledge is to be as an instance of knowledge and would have to be the same propositions as (1). But then how can (1) be informative when (2) is not? This is what is called the first paradox of analysis. Classical writing on analysis suggests a second paradoxical analysis (Moore, 1942).
(3) an analysis of the concept of being a brother is that to be
a Brother is to be a male sibling. If (3) is true, it would seem that the concept of being a brother would have to be the same concept as the concept of being a male sibling and tat:
(4) An analysis of the concept of being a brother is that to be a brother is to be a brother would also have to be true and in fact, would have to be the same proposition as (3?). Yet (3) is true and (4) is false.
Both these paradoxes rest upon the assumptions that analysis is a relation between concepts, than one involving entity of other sorts, such as linguistic expressions, and tat in a true analysis, analysand and analysandum are the same concepts. Both these assumptions are explicit in Moore, but some of the writing that Moore hints at, is a solution to that of another statement of an analysis is a statement partly about the concept involved and partly absolute in the expressions used to express it. He says he thinks a solution of this sort is bound to be right, but fails to suggest one because he cannot see a way in which the analysis can be even partly about the expression (Moore, 1942).
